WebMar 15, 2008 · Clustered ordinal data have the extra complexity that observations within each cluster are also multivariate due to their multinomial nature. Fitzmaurice (1995) … WebUse GEE when you're interested in uncovering the population average effect of a covariate vs. the individual specific effect. These two things are only equivalent in linear models, but not in non-linear (e.g. logistic). To see this, take, for example the random effects logistic model of the j 'th observation of the i 'th subject, Y i j;
